Idl plot manual

• The text Practical IDL Programming by Liam E. Gumley () is a useful resource for beginning and expert IDL users. • Using IDL to Manipulate and Visualize Scientific Data by Bill Davis. IDL plot, x, y, linestyle = 2 • Use the thick keyword to change the thickness of the line plots. For example if you want to plot displayed with a dashed line that is three times thicker than normal try: IDL plot, x, y, linestyle = 2, thick = 3 19File Size: KB. Plotting Symbols IDL contains a number of symbolsready for your use. The symbols are designated using keywords with the Plotcommand such as: Plot, xvalues, yvalues, PSym=-5, SymSize= SymSize=2 makes the symbols twice as big as "normal." This command draws a graph with xvalues on the x axis, yvalues on the.

Create an annotation legend for a plot. Explanation This procedure makes a legend for a plot. The legend can contain a mixture of symbols, linestyles, Hershey characters (vectorfont), and filled polygons (usersym). (D=1) usersym = 2-D array of vertices, cf. usersym in IDL manual. (/USERSYM =square, default is to use existing USERSYM. The Interactive Data Language Intrinsic IDL: written by Exelis and described in the IDL manuals and online help system invoked by the? command. Intrinsic IDL code is proprietary. The basic IDL commands for making plots are plot, for creating a new plot, and oplot, for overplotting on an existing plot. 1 Answer1. Show activity on this post. I believe the only way to create a PDF directly in IDL is through function graphics, i.e., the PLOT () function. To do it from direct graphics, like you have above, create a PostScript file and convert it to a PDF using some other utility like www.doorway.ru or ImageMagick.

To plot one vector as a function of another, use two parameters. Instead of data, you can also input an equation of X using either the input argument or the EQUATION property. In this case IDL will automatically generate the independent X data and use your equation to compute the dependent Y data. IDL contains a number of symbols ready for your use. The symbols are designated using keywords with the Plot command such as: Plot, xvalues, yvalues, PSym=-5, SymSize= SymSize=2 makes the symbols twice as big as "normal." This command draws a graph with xvalues on the x axis, yvalues on the y axis, and the points are indicated by a triangle. To reset to the IDL default values for an individual plot: PLOT,W,F,XMARGIN=[10,3],YMARGIN=[4,2] Multiple plots of equal size can be arranged on one page by setting the system variable!www.doorway.ru, which is a vector specifying the number of plots in the horizontal and vertical directions.
